Hello,

Just moved into a pre-owned home built in 1999. Ranch on a slab. Copper pipes in slab.
Under bath faucets there are gray plastic lines from the copper lines to the faucets.

Any idea what the plastic line are? What are they made of? Should I replace them with
stainless steel flex hoses for safety concerns?

I don't want one of the plastic hoses bursting one me.

Thanks for thoughts/ideas.

Bill
